History of Tylok
In the mid-1940s, Cullen Crawford developed and patented the original flare-less fitting (nut & double ferrule system), making it easier and more efficient to make tubing connections. Based on this innovation, he founded the Crawford Fitting Company, creating an industry for compression fittings. Now, Tylok has been manufacturing its products in the USA for 69 years. We are continuing to innovate and provide quality-driven products to our customers.

Descriptions
Pipe Fitting Tees by Tylok are fully interchangeable with Swagelok, Parker A-Lok™, and Parker CPI™ fittings, offering compatibility and reliability for branching pipe connections. These fittings ensure a leak-proof seal through precise ferrule action, where the ferrules tighten onto the tubing via axial thrust provided by the nut. Proper tightening to the specified number of turns guarantees a secure and durable connection. Tylok Pipe Fitting Tees are available in stainless steel, brass, and carbon steel, providing flexibility for various industrial applications. Their robust construction and interchangeability make them a dependable choice for creating three-way connections in piping systems.
